PROPERTIES OF CONCRETE  COMPRESSIVE STRENGTH GRADE OF CONCRETE The compressive strength of concrete is the characteristic compressive strength (/cel of 150 mm concrete cubes at the age of 28 days in N/mm². IS 456-2000 specifies the characteristic compressive strength of 150 mm cube at the age of 28 days in N/mm², as the Grades of … Read more

Q. If liquid pressure is increased from 4000 kN/m² to (b) Ir 6000 kN/m², the volume of liquid decreased by 0.2 percent, Determine the bulk modulus of elasticity of the liquid.

Q. If liquid pressure is increased from 4000 kN/m² to (b) Ir 6000 kN/m², the volume of liquid decreased by 0.2 percent, Determine the bulk modulus of elasticity of the liquid. SOLUTION: Bulk modulus of elasticity K = – (dp)/((dv)/v) Change in pressure p = 6000 – 4000 = 2000kN / (m ^ 2) =(dv)/v … Read more
